Lots of Chinese transformer bobbin manufacturers have got export licenses which allow the goods to be cleared via China Customs. This is a big change compared to this in 1997. The producers who lack export licenses are normally smaller manufacturers who behave as specialized subcontractors. They only focus on making a specific kind of material, processing or component for a bigger - and more export oriented-maker. You are expected to use producers that have export licenses or trading businesses who partner with manufacturers in the long run.
